Claude-enhanced Reading Edition
The Marginal Revolution: Reimagined
Tyler Cowen's exploration of marginalism, restructured into twelve focused chapters by Claude — with enrichment stories, contextual footnotes, and narrative threads woven through the original arguments, then refined across multiple rounds of agent-driven evaluation.
The Original
Tyler Cowen published The Marginal Revolution: Rise and Decline, and the Pending AI Revolution through the Mercatus Center at George Mason University in early 2026 — roughly 65,000 words across four expansive chapters tracing marginalism from Galileo through Jevons, Walras, and Menger to the AI frontier. Read the original here.
What We Did
Claude restructured Cowen's four long chapters into twelve shorter, more focused ones — each between five and eight pages. Every chapter received an enrichment story woven into the argument, contextual footnotes written by Claude, and a disclosure showing exactly what changed. Then scoring agents evaluated each chapter across ten dimensions and generated targeted improvements over three rounds. See how the agents did it.
